CRIMPED JOINT non BATHROOM-FIXTURES.

Application filed September 7 '0 all whom it may concern:

Be it known that 1, WILLIAM R. GRInRsoN, a citizen of the United States, residing at Waterbury, in the State of Connecticut, have invented a new and useful Improvement in Crimped Joints for Bathroom-Fixtures; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application and represent, in

Figure 1, a broken plan view of a bathroom fixture embodying my invention.

Fig. 2, a view thereof in side elevation- Fig. 3, a reverse plan view thereof.

Fig. 4, a detached plan view of the struckup mounting plate before spiling the same.

Fig. 5, a view thereof in vertical central section.

Fig. 6, a plan view of the plate after spiling.

Fig. 7, a view thereof in vertical central section.

Fig. 8, a broken view in side elevation of the struck-up end of the tubular member of the fixture.

Fig. 9, an enlarged broken reverse plan view showing the crimping of the assembling flange of the tubular member into the notches of the mounting-plate.

Fig. 10 a broken sectional View of the tubular member and mounting-plate, showing the spiling of the latter.

My invention relates to an improved crimped joint for bathroom fixtures such as towel-racks; soap-dish holders; sponge-cup holders; drinking-glass holders and kindred conveniences, the object being to provide improved means of securing the mountingplates and tubular members of such fixtures together in a firm and neat manner without the use of screw threads or of solder.

\Vith these ends in view my invention consists in an improved joint for bathroom fix tures, havingcertain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, the central boss 10 of the struck-up mounting-plate 11 is initially formed with a concentric hole 12 having four equidistant radiating slots 13 as shown in Fig. 4. Pref- Specification of Letters Patent.

Patented Nov. 1, 1921.

Serial No. 409,892.

erably the plate 11 will have the form of a disk and is so shown, but this is not essential. The plate is also formed with screwholes 14. The plate is now subjected to the action of a spiling tool, whereby its concentric hole 12 is enlarged to form a concentric assembling-opening 15, as shown in Figs. 6 and 7, this opening being produced by turning inward at a right-angle to the plane of the plate, the four segments 16 of.

metal lying between the radial slots 13 of the plate as shown in Fig. 4. The described turning inward of the segments 16 is permitted by the radial slots 13 which are now stretched open to form the lockingnotches 17.

Into such a mounting-plate as thus described, 1 insert the struck-up end of the tubular member 18 of the fixture,the said end being struck-up to form an abutmentbead 19 and a locking-sleeve 20, the latter being inserted into the assembling-opening 15 so as to bring the bead 19 to a bearing upon the annular face 21 of the plate 11. The two parts as thus joined are subjected to the action of dies, whereby the sleeve 20 of the tubular member 18 is shaped to form four outwardly flaring equidistant flutes or orimps 22 which respectively enter the four crimp-receiving notches 16 of the mounting-plate as clearly shown in Figs. 3 and 9. Thev mounting-plate and tubular member are thus solidly fastened together without the use of screw threads and with out the use of solder, the former method requiring the employment of expensive and heavy stock and the latter being neither strong nor finished in appearance. Under my improved construction the crimping or fluting of the locking-sleeve of the tubular member, is a localized displacement of metal rather than a diffused upsetting thereof, as when the end of a tube is expanded symmetrically.

I claim:

1. A bathroom fixture having a struck-up mounting-plate and a tubular member, the former being provided with crimp-receiving notches and the latter'being formed with an assembling flange crimped to produce locking-flutes entering the said notches for unit ing the two parts.

2. A. bathroom fixture having a struck-up fastening plate and a tubular member, the

former having spiled an assembling opening surrounded by segmental flanges separated by crimp-receiving notches, and the latter having an abutment-bead and an assembling sleeve which is crimped to "form locking-flutes entering the said notches for holding the two parts together.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

WVILLIAM 'R. GRIERSON.
